Key Takeaways
- USDC is a fully collateralized stablecoin issued by Circle, always redeemable 1:1 for US dollars.
- Every blockchain has its own unique USDC contract address — using the wrong one can result in permanent fund loss.
- Always verify any USDC address against Circle's official developer documentation before sending funds.
- Testnet USDC addresses carry no real financial value and should only be used for development and testing.
- When adding USDC to MetaMask, make sure the contract address matches the network you are connected to.
- You can verify any USDC contract address on-chain using block explorers like Etherscan, PolygonScan, or Solscan.
USDC Contract Address: Official Mainnet Addresses by Blockchain
USDC is a fully collateralized US dollar stablecoin issued by Circle, running natively across multiple blockchains.
Each chain has its own unique USDC contract address — and using the wrong one could mean losing your funds permanently.
The table below lists the official USDC token address for every major mainnet, sourced directly from Circle's documentation.
Blockchain | USDC Contract Address / Mint Address |
Ethereum (ERC-20) | |
Polygon PoS | |
Solana | |
Arbitrum | 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 |
Base | 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 |
Avalanche C-Chain | 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E |
OP Mainnet | 0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85 |

Always double-check these addresses against Circle's official USDC documentation before sending any funds — one wrong character can result in an irreversible loss.
USDC Testnet Contract Address: Sepolia, Devnet & More
If you're a developer testing a DeFi app or smart contract, you'll need testnet USDC addresses — not mainnet ones.
It's important to understand that testnet USDC tokens carry no real financial value and are not backed by actual US dollars.
Here are the key USDC contract addresses for the most common testnets:
Testnet | USDC Address |
Sepolia (Ethereum testnet) | Refer to Circle's official developer documentation for the latest testnet USDC contract addresses, as these are subject to change. |
Base Sepolia | Refer to Circle's official developer documentation for the latest testnet USDC contract addresses, as these are subject to change. |
Arbitrum Sepolia | Refer to Circle's official developer documentation for the latest testnet USDC contract addresses, as these are subject to change. |
Solana Devnet | Available via Circle's devnet faucet |
For the most up-to-date testnet USDC addresses, always refer to Circle's official developer documentation, since testnet addresses can change with network upgrades.
How to Add USDC Token Address to MetaMask
Adding USDC to MetaMask is simple — but choosing the right network and contract address is critical.
- Open MetaMask and make sure you're connected to the correct network (e.g., Ethereum Mainnet or Polygon).
- Click "Import tokens" at the bottom of the Assets tab.
- Paste the correct USDC contract address for your chosen network — for Ethereum, use
0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48.
Learn more about the ERC-20 standard: What is USDC ERC20? - MetaMask will auto-fill the token symbol (USDC) and decimals (6) — verify these match before confirming.
- Click "Add Custom Token," then "Import Tokens" to complete the process.
- If you're on Polygon, use the Polygon PoS USDC address
0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359instead of the Ethereum one. - Never use an address from unofficial sources — always verify against Circle's documentation or CoinGecko's token page.
Common USDC Wallet Address Mistakes to Avoid
Sending USDC to the wrong address is one of the most common — and costliest — mistakes in crypto.
- Sending ERC-20 USDC to a Solana address will result in permanent loss of funds, since the two networks are not cross-compatible by default.
- Using an old bridged USDC address (like USDbC on Base) instead of the native USDC address can cause transaction failures or send funds to the wrong contract.
- Confusing a USDT address with a USDC address is an easy mistake — always verify the token symbol before confirming any transaction.
- Sending USDC on the wrong network (e.g., Polygon USDC to an Ethereum wallet expecting ERC-20) may result in unrecoverable funds.
- Copy-paste errors are more common than you think — always verify the first and last 4–6 characters of a USDC wallet address before sending.
- Never trust a USDC contract address shared via social media, Discord, or email — scammers frequently impersonate Circle and other official sources.
FAQ
What is a USDC address?
A USDC address is the unique smart contract address or wallet address used to send, receive, or interact with USDC tokens on a specific blockchain.
What is a USDC wallet address?
A USDC wallet address is the public address of any crypto wallet that holds USDC — it works the same as any other blockchain wallet address on that network.
How do I get a USDC wallet address?
You can get a USDC wallet address by creating a wallet on any compatible network (such as MetaMask for EVM chains or Phantom for Solana) — your wallet address automatically supports USDC once you import the token.
Can I send USDC to an ETH address?
Yes — if both the sender and receiver are using the same network (e.g., Ethereum Mainnet), sending USDC to an ETH-format address works fine.
What happens if I send USDT to a USDC address?
Since USDT and USDC are different tokens with separate contract addresses, sending USDT to a USDC-specific contract address may result in permanent loss of funds.
Is there a USDC address checker I can use?
Yes — you can verify any USDC contract address using blockchain explorers like Etherscan (Ethereum), Polygonscan (Polygon), or Solscan (Solana), and cross-reference against Circle's official documentation.
What is the USDC mint address on Solana?
The official USDC mint address on Solana mainnet is

USDC runs across multiple blockchains, and every single one has its own unique contract address.
One wrong address can mean lost funds with no way to recover them.
Always verify the USDC token address directly from Circle's official documentation or a trusted data source like CoinGecko before any transaction.
You can buy and trade USDC on MEXC with a straightforward process and deep liquidity across multiple trading pairs.
